Leaf-mine: An irregular whitish linear mine which can broaden at end and become blotch-like (Spencer, 1976: 397).

Larva: The larvae of flies are leg-less maggots without a head capsule (see examples). They never have thoracic or abdominal legs. They do not have chewing mouthparts, although they do have a characteristic cephalo-pharyngeal skeleton (see examples), usually visible internally through the body wall. The larvae lie on their sides within the mine and use their pick-like mouthparts to feed on plant tissue.

Posterior spiracules two-horned with about 20 bulbs (de Meijere, 1937a) (Bladmineerders van Europa).

Puparium: The puparia of flies are formed within the hardened last larval skin or puparium and as a result sheaths enclosing head appendages, wings and legs are not visible externally (see examples).

Black; posterior spiracles each with an ellipse of some 20 bulbs (Spencer, 1976: 397).
